A model for consumers' response to advertising is given by N(a) = 2000 + 500 In a, a 2 1, where N(a) is the number of units sold and a is the amount spent on advertising, in thousands of dollars. a. How many units are sold when $1000 is spent on advertising? b. Find N (a) and N (10). c. How much should be spent on advertising if 3000 units are to be sold? d. [Writing exercise.] Find lim N (a). Does it make sense to continue to spend more and more on advertising? Why or why not? 26. Advertising. A model for consumers' response to advertising is given by N(a) = 1000 + 200 In a, a > 1, where N(a) is the number of units sold and a is the amount spent on advertising, in thousands of dollars. a. How many units are sold when $1000 is spent on advertising? b. Find N (a) and N (10). c. How much should be spent on advertising if 1500 units are to be sold? d. [Writing exercise.] Discuss lim N (a). Does it make sense to spend more and more on advertising? Why or why not? 27. Marginal revenue. The demand for a new computer game can be modeled by p(x) = 53.5 – 8 In x, for 0 < x < 800, where p(x) is the price consumers will pay, in dollars, and x is the number of games sold, in thousands. Recall that total revenue is given by R(x) = x · p (x). a. Find R(x). b. Find the marginal revenue, R (x). c. How many units will be sold if the price that consumers are willing to pay is $40?

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
